PUMP.

SPECIFICATION forming part of Letters '.Patent No. 564,080, dated July14, 1896.

Application filed July 17, 1895.

lfor its object to provide a pump of the character indicated whichisvery simple, cheap, and effective.

The invention consists in the particular construction and arrangement ofparts, as hereinafter fully described, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a partofthis specification,

in which similar letters of reference refer to.

corresponding parts in all the views.

Figure 1 is a perspective view of the improvement. Fig. 2 is a sectionon line 2 2 of Fig. 3 is a section on line 3 3 of Fig. 2, and Fig. 4l isa perspective view of the pistons.

vA is a cylindrical casing mounted upon a suitable base or support B,and O is a waterchest above the casing and divided by the partition cinto two compartments c and c2, communicating at the bottom with thesaid casing. Inlet-pipes D D communicate with the upper part of thecasing A through 'ports d d/ in the casing adjacent to the chest C, andthe compartments c' and c2 of the chest are connected with thedischarge-pipe E by the branch pipes e and e', leading from the saidcompartments, respectively.

Within the casing A are mounted the eccentric and oppositely-arrangedpistons F and F2, which travel on the inner surface of the casing andalternately force the water out of the casing into the compartments ofthe chest, as hereinafter-more fully explained.

As shown in the drawings, the pistons F and F2 are formed by groovingthe solid cylinder F, as shown at f and f', to form two eccentrics,whichare oppositely arrangedwith respect tov each other. The cylinder F fitssnugly in the casing A and virtually divides the casing into twocompartments, one for each of the compartments of the chest C. From theends of the cylinder project the serial No. 555,251. (No man.)

trunnions f2 and f3, which are mounted in the bearings a and a of thecasing. The trunnion f2 is provided with a pulley f4, by means of whichthe cylinder can be operated. Within the casing A, at the upper partthereof and adjacent to the inlet-ports d d', are hinged the valves Gand G', whose free ends fit in the grooves f and f and rest upon thepistons as th eytravel around in the casing,so that the Water forcedupward by the pistons is prevented from passing in rear of the saidpistons and consequently will be forced by the pistons into thecompartments of the chest O.

- In order to prevent back pressure of the Water in the discharge-pipe Ewhile the pistons are passing the valves Gand G', a checkvalve e2 isarranged in the said dischargepipe. 4

The operation is as follows: Power being applied to the pistons torevolve them in the direction of the arrow, Fig. 2, the water will bedrawn in through the inlet-pipes D D', and as the pistons continue torevolve in contact with the inner surface of the casing the water whichhad previously entered the casing and is in front of the pistons will beforced upward and out into the compartments of the chest O, and fromthence out through the branch pipes e and e' into the discharge-pipe E.It will of course be understood that the pistons act alternately toforce the water from the casing into its respective compartments ofthe'chest, so that a continuous stream of `Water will be discharged bythe pump.

l/Vhile I have shown but two eccentrics, yet it is obvious that more maybe employed if desired.

Having thus described my invention, what v I claim, and desire to secureby Letters Patent, is-

l. In a pump, the combination with a casing having, an inlet and outlet,of eccentric and oppositely-arranged pistons mounted to rotate in thecasing, said pistons being integral and dividing the casing intocompartments, and hinged valves resting upon the pistons, substantiallyas described.

2. In a pump, the combination with a casing having an inlet and outlet,of a cylinder mounted in the casing and formed with eccentric andoppositely-arranged pistons, said IOO of a cylinder mounted in theeasing and` formed with two eccentric and oppositely-arranged pistons,said cylinder fitting snugly in y the casing and dividing. it into twocompartments one for each of the compartments of the chest, and hingedvalves resting upon the pistons, substantially as described.

4. In a pump, the combination with a casing having an inlet anddischarge, of a solid revoluble cylinder fitting in the casing andprovided with grooves for-ming tivo oppositely-arran ged eccentricpistons said cylinder fitting snugly in the casing and dividing it intocompartments, and valves resting upon the pistons, substantially asdescribed.

5. In a pump, the combination with a casing, a chest above the casingand provided with two compartments, each communicating with the casin g,a valved discharge-pipe connected with the said compartments, andinletpipes opening into the upper part of the casing, of a solidrotatable cylinder in the casing and provided with grooves, forming twoopi positely-arranged eccentric pistons, said cyl inder fitting snuglyin the casing and dividing it into two compartments, one for each of thecompartments of the chest and valves hinged to the upper part of thecasing and having their free ends resting upon the pistons,substantially as described.

6. In a pump, the combination with a casing provided with inlet-pipesleading into the upper part of the casing through the side thereof, achest above the casin g and provided with two compartments communicatingwith the casing, a valved discharge-pipe connected with each compartmentof the chest, of a solid cylinder mounted to revolve in the casin g andprovided with two annular grooves forming two oppositely-arrangedpistons, said cylinder fitting snugly in the casin g and dividing itinto two compartments, one foreach compartment of the chest, and valveshinged to the upper part of the casing in front of and adjacent to theinlet-pipes, and having their free ends resting upon the pistons,substantially as herein shown and described.
